The use of "on purpose"

[kachibi]

"On purpose" in the dictionary means intentional, deliberate:
-"Someone set fire on purpose."
-"I knew she had not done it on purpose."

It seems that "on purpose" has somewhat a negative feeling (like having some bad intentions/attempts). I wonder if I can use it if I simply want to say I do something for some normal reasons/ purposes. Like I am already a graduate but I sometimes go back to the campus to find my friends, take photos around, read books in the main library, etc:

"I will not go back to the campus for no reasons. Every time I visited the campus ON PURPOSE.(for doing the set of things above)"

is it correct?

Your example is not good. But the answer to your question is that "on purpose" does not have to have a negative connotation.
For example, a man takes his wife to the theatre, and they plan to sit in the cheap seats. He comes back from the ticket office with tickets for the expensive seats.
Wife: You've made a mistake and bought the wrong tickets! You paid too much!
Husband: No, I paid the extra on purpose, to give you a special treat.
